CURTIS DC Speed Controller 1243-4320 300A 16kHZ

Notice: For the buyer without ConTROLLER APPLYING EXPERIENCE, please consult your cart/motor dealer and read carefully the 1243 Controller Manual (PDF format) before making the purchase.

If you need to modify any controller parameter, please send us a message with the list of parameters to be modified (Click here to download the parameter list of default setting of controller 1243-4320, PDF format).

Notice: We supply also the 1243-4320 controller assemblage with throttle (control handle).

Overview:

CURTIS 1243 Generation 2 MultiMode™ controllers are separately excited motor speed controllers designed for use in a variety of small industrial vehicles and in material handling equipment. These programmable controllers are simple to install, efficient, and cost effective, while offering more features than the original 1243.

The 1243 GEN2 MultiMode™ controller provides smooth precise control of motor speed and torque. A full-bridge field control stage is combined with a half-bridge armature power stage to provide solid state motor reversing and full regenerative braking without additional relays or contactors. The controller's rugged IP53 housing and packaging are built to withstand shock and vibration. State-of-the-art surface mount logic board fabrication makes the 1243GEN2 controller even more reliable than the original 1243. The 1243GEN2 is fully programmable through the CURTIS Model 1313-4331 Handheld Programmer or 1314 PC Programming Station. In addition to configuration flexibility, the programmer provides diagnostic and test capability.

Appropriate throttles for use with the 1243-4220 controller include:

Type 1: 2-wire 5kΩ-0 throttlesType 2: 0-5V throttles, current source throttles, three-wire potentiometer throttles, and electronic throttles wired for singleended operationType 3: 2-wire 0-5kΩ throttlesType 4: 0-5V and three-wire potentiometer throttles wired for wigwag operation
